The goal of this project is to determine and validate energy savings for a typical retrofit for two delta T valves in an HVAC chiller system. Delta T is the difference between the water supply and return temperature across a cooling coil. When downstream cooling coils have a low delta T, it can...

Phase change materials (PCMs) are latent thermal energy storage products designed to offset building cooling requirements of HVAC systems. This field study seeks to evaluate the effect of installing PCMs in a quick-service restaurant to quantify the demand and energy savings benefits from...

The goal of this project is to understand the role of middlemen in advanced economizer controls for commercial HVAC systems. More specifically, the project looks at the role human factors play in the adoption and successful utilization of advanced economizer controls. Ultimately, the objective is...

This project will draft a Building Energy Simulation (BES) Roadmap, given SCE’s reliance on Building Energy Simulation (BES) tools and pivotal role within the BES arena. This roadmap will help SCE: promote transparency and cross-collaboration amongst SCE’s IDSM programs, optimize future...

Evaluate performance of HVAC and refrigeration applications using advanced refrigerants. This project intends to explore and document advances in product development for advanced refrigerants in the refrigeration and HVAC...

The goal of this project is to develop a methodology for determining the potential energy and peak-demand savings associated with sealing large buildings: commercial, hospitality, and dormitory style buildings. This includes developing models for the energy use and demand associated with leakage in...

Evaluation of performance of ultra-low temperature lab freezers. The technology replaces the cascade systems to achieve ultra-low cabinet space refrigeration temperatures (-86°C) used in the medical research, life science, pharmaceutical and clinical hospital...

Southern California Edison will be presented with more and more ideas for program offerings that are styled as "behavioral" offerings; however, whether these offerings do have an effect on energy savings behaviors is unknown. This standardized scale will allow SCE to assess the relative...

This project is to assess the state of LED tubes for retrofitting linear fluorescent lamps used in recessed troffer applications. The options range from simple lamp only replacements to full lamp and ballast retrofits. The assessment would include research for existing literature on specifications...

The Solar Decathlon is a DOE-sponsored international competition which challenges collegiate teams to design, build, and operate solar powered houses that are cost-effective and energy-efficient. These competition homes are highly visible and typically see more than a quarter of a million visitors....
